ETA Scheduler Agent (ESA)

You have a dentist appointment at 3:00 across town. You know this. What you don't know, at 2:35, is that the ring road is jammed. The ETA Scheduler Agent (ESA) does: for any event with a real address, it computes traffic-aware travel time, drops a "Leave for …" block on your calendar, and sends a leave-now reminder at exactly the right moment. And when the event is a flight, it knows the drive to the airport is only half the story — it budgets your check-in, security, and boarding time too, so "leave now" means leave now.

It's the least chatty agent in the crew — no LLM involved, just live routing data and arithmetic — and quietly one of the most useful. It's included in your plan, no add-on required.

Turning it on

Settings → AI Agents → ETA Scheduler. It's off by default, because it needs to know where you start from:

• Home address — where you leave from by default.
• Work address — used as the starting point instead of home during your working hours.
• Travel by — Driving, Transit, Walking, or Cycling. Your default, overridable per event.
• Buffer — extra minutes shaved off the departure time, for the coat, the keys, and the elevator.
• Smart prep time — on by default. Some events need you there well before they start — a flight isn't a coffee. Fokus detects the kind of event and adds that on-the-ground lead time on top of the drive, so the departure block covers check-in and security, not just the traffic. Tune it per category:
  • Flight — time at the airport before departure (check-in, security, boarding). Default 120 min.
  • Train — time at the station before it leaves. Default 25 min.
  • Ferry — time at the port. Default 45 min.
  • Medical — arrive early to check in. Default 15 min.

What it does, exactly

When an event qualifies, Fokus:

1. Figures out where you're coming from. If another in-person event ends shortly before (within three hours), it routes from there. Otherwise it uses your home address — or your work address if the trip starts during working hours.
2. Asks for live travel time for your chosen mode, accounting for current traffic.
3. Adds any prep time the event needs. A flight, train, ferry, or medical appointment gets its category lead time (above) layered on top of the drive — so the plan accounts for getting there and getting through the airport, not just the road.
4. Blocks it on your calendar, titled after the event and spanning the whole window — travel plus prep — so the commute and the check-in queue both stay protected.
5. Attaches a "leave now" reminder that arrives through your normal notification channels.

It's idempotent and self-maintaining: move the event, change its location, switch travel mode, or delete it entirely, and the travel block updates or disappears with it. Traffic is also re-checked every 30 minutes for events starting in the next three hours — so if the road jams up after the block was created, your departure time moves earlier and the reminder follows.

Which events qualify

An event gets a travel block when all of these hold:

• It has a physical address (a Zoom link doesn't count — nobody needs to leave early for that).
• It isn't an all-day event, and it isn't cancelled.
• It starts in the future, within the next 7 days.
• You haven't declined the invitation.

Everything else is skipped silently. Travel blocks themselves are never given travel blocks — the Captain thought of that.

Per-event travel mode

Usually driving but taking the train to this one? Set the travel mode on the event itself (the field is right there when you create or edit it) and ETA uses it for that trip only, leaving your default untouched.
